New video on the CopperSpice YouTube Channel:
std::launder
by Barbara Geller and Ansel Sermersheim
About the video:
Our recent C++ video started a lively conversation. We showed a use case for std::launder which caught several developers off guard. A new compiler setting was enabled which exposed a problem in our existing code. Please watch the full video to find out what we learned.

Template Design With Policy Classes
by Barbara Geller and Ansel Sermersheim
About the video:
We have a new C++ video which discusses Policy Based Design and compares it to other styles of programming. Do you know which design pattern policy based programming solves? Have you considered the benefits of a design which provides a solution at compile time versus run time? Are you using policies and maybe you had no idea they had a name?

Registration is now open for CppCon 2024! The conference starts on September 15 and will be held in person in Aurora, CO. To whet your appetite for this year’s conference, we’re posting videos of some of the top-rated talks from last year's conference. Here’s another CppCon talk video we hope you will enjoy – and why not register today for CppCon 2024!
Undefined Behavior in C++: What Every Programmer Should Know and Fear
by Fedor Pikus
Summary of the talk:
This talk is about You-Know-What, the thing in our programs we don’t mention by name.
What is this undefined behavior every C++ programmer has grown to fear? Just as importantly, what it isn’t? If it’s so scary, why is it allowed to exist in the language?
The aim of this talk is to approach undefined behavior rationally: without fear but with due caution. We will learn why the standard allows undefined behavior in the first place, what actually happens when a program does something the standard calls “undefined,” and why it must be taken seriously even when the program “works as-is.” As this is a practical talk, we will have live demos of programs with undefined behavior and sometimes unexpected outcomes (if you are very lucky, you might see demons fly out of the speaker’s nose). Also, as this is a practical talk, we will learn how to detect undefined behavior in one’s programs, and how to take advantage of the undefined behavior to gain better performance.

Lightning Talk: Thread Safety With synchronized_value in C++
by Jørgen Fogh
Summary of the talk:
Adding thread safety to existing code is hard. The proposed type synchronized_value makes it less hard.
I will show you why.

Lightning Talk: The Responsibility of C++
by Neil Henderson
Summary of the talk:
Hopefully an amusing and light-hearted look at C++ and its strengths and responsibilities in the software world from a recent life-changing experience.

CppCon 2023 std::linalg: Linear Algebra Coming to Standard C++
by Mark Hoemmen
Summary of the talk:
Many fields depend on linear algebra computations, which include matrix-matrix and matrix-vector multiplies, triangular solves, dot products, and norms. It's hard to implement these fast and accurately for all kinds of number types and data layouts. Wouldn't it be nice if C++ had a built-in library for doing that? Wouldn't it be even nicer if this library used C++ idioms instead of what developers have to do now, which is write nonportable, unsafe, verbose code for calling into an optimized Fortran or C library?
The std::linalg library does just that. It uses the new C++23 feature mdspan to represent matrices and vectors. The library builds on the long history and solid theoretical foundation of the BLAS (Basic Linear Algebra Subroutines), a standard C and Fortran interface with many optimized implementations. The C++ Standard Committee is currently reviewing std::linalg for C++26. The library already has two implementations that work with C++17 or newer compilers, and can take advantage of vendor-specific optimizations. Developers will see how std::linalg can make their C++ safer and more concise without sacrificing performance for use cases that existing BLAS libraries already optimize, while opening up new use cases and potential optimizations.
